Ears,Extendable
Eavesdropping device; one of
Weasleys' Wizard Wheezes (see).
An Extendable Ear looks like a piece of flesh-coloured string. One end is inserted into a person's
ear, then, on the command "Go," the other end wriggles off to
where a conversation is taking place. The Extendable Ear makes the distant
conversation easily discernable
